SPECIFICATION forming part of Letters Patent No. 499,169, dated June 6, 1893. 7

Application filed June 16, 1892. Serial No. 436,981. (No model.)

To all whom it may concern.-

Be it known that I, MAURICE KANE, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvementsrelative position the drive wheel of a harvester and certain portions of the frame, the stubbleward end of the platform-conveyor, the grainward end of the binder deck and the binding arm, and showing, in detail, the construction of the elevator and devices at the delivery side of the platform conveyer which constitute my invention. Fig. 2 is a detail sectional view of the delivery side of the platform conveyer and receiving side of the ele-' vator, showing a slight modification with respect to the platform-conveyer-delivering mechanism. Fig. 3 is a detail sectional elevation of the devices shown in Fig. 1, section being made at the line 33, the view being taken looking stubbleward.

A is the platform conveyer apron or canvas. A is its driving roller at the delivering side. In Fig. 1, I have shown alarge driving roller, whose upper side is above the level of the carrying surface of the apron, the latter being held to the level at which it is designed to travel over the platform by shoes B B, secured to the front and rear sills a, a, and overhanging the edges of the apron, so as to engage the stiffening slats a thereon as the apron moves toward the dischargeside, the grainward end of the shoe being upturned, as seen in Fig. -1, to insure the entrance of the slats under the shoe as the apron moves. In Fig. 2, the driving roller A isshown of less size, not requiring the shoes, but located farther grainward than the larger roller of Fig. 1, and being supplemented by aclearing or delivering roller A parallel with the roller A, and just grainward therefrom. When the larger roller A is employed, it is preferably located considerably grainward from the vertical line of the driving roller. of the elevator apron, so that said driving roller overhangs the shoes and the portion of the platform carrier apron which is inclined in the passage from the lower level of the carrier to the higher level of the upperside of the large roller A. Whichever form of device is employed at the delivery side of the platform carrier, Iprovide, to receive the grain therefrom, whether delivered directly by the apron passing over the larger roller A or by the small roller A taking the grain from the platform carrier, the deck C, which extends in an upwardly inclined direction to the top of the drive wheel and over the same as close thereto as possible without interfering with the proper adjustment of the machine on the drive wheel, and thence down at the stubbleward side of the wheel to the binder deck D. In order to carry the grain up this inclined deck and on over the Wheel, and cause it to be delivered therefrom onto the binder deck, I provide an endless carrier E, which I prefer to make in the form of an apron passing'over a driving roller F, at the lower inner side, said driving roller and the ,receiving end of the carrier, therefore, overhanging the platform carrier, and being located somewhat grainward from the point where the grain is delivered therefrom onto the fixed inclined deck C. When the platform carrier apron is extended stub-- when the apron is restrained by the shoe B,

as shown in Fig. 1, I prefer to have the said driving roller of the elevator andthe receiving end of the latter overhang the upwardly concave portion of the platform carrier apron, which extends from the horizontal portion up to the upper side of the large driving roller A of said platform carrier. In a similar manner, when a clearing roller A is employed to supplement a platform carrier, which is horizontal and without the up-rise at the delivery side caused by the larger roller, I prefer to have the elevator receiving end and driving roller overhang the corresponding space between the horizontal platform carrier and the receiving end of the deck 0. At the upper and delivery side, the endless elevator carrier E passes around the roller G, which is located stubbleward from the vertical foreand-aft plane of the drive wheel K, the upwardly moving and grain-actuating ply of the carrier E being deflected by shoes H H, secured to the elevator frame, and operating similarly to the shoes B B, provided for the platform carrier in the form shown in Fig. 1, and tending to deflect the grain-actuating ply of the endless carrier upward, forming a downwardly open obtuse bend at about the vertical plain of the grainward side of the drive wheel; and, to retain the return ply of the carrierin a correspondin g position and prevent it from dragging on the lower grain-actuating ply,I provide the idle roller J, suitably journaled in the frame atsuch position above the grain-actuating ply, and near the vertical plane of the grainward side of the drive wheel, as to permit the grain-actuating ply to be forced up as far as necessary by the grain which is carried by said ply, to give it throat room or opportunity for passage over the wheel toward the binder. As Iprefer to construct the elevating mechanism, however, the grain-actuating ply is not liable to be forced very much out of what may be considered its normal position on the shoes H; for I prefer to employ stripping bands L L L, which may be strips of sheet metal, having their ends at the grainward side of the elevator secured to the seat plank I, and extending around underneath the driving roller F of the elevator endless carrier and therefrom substantially parallel with the deck 0 in the inclined direction of that deck, and over the portion of said deck which overhangs the drive wheel, leaving a throat or avenue of approximately uniform width to a point about in the vertical plane of the farther side of the drive wheel or alittle beyond it, and from that point, being deflected upward away from the deck 0, but still away from the endless carrier E, in close proximity to which the strippers have extended throughout the upwardly inclined portion of their course, grainwardfrom the wheel, and the approximately horizontal portion, above the wheel, and from which they now diverge in order that the carrying teeth E E, the, with which the endless carrier of the apron is provided, may be stripped before they pass over the outer roller Gr. The stubbleward and upper ends of the strippers L may be secured to a transverse bar M, which is located at the stubbleward side of the wheel beyond the roller G, and overhanging the binder deck D. The usual floating fingers N, secured at any convenient point stubbleward from the elevator carrier, serve to check the grain on the binder deck D, so that as it is delivered by the carrier from the widening mouth formed between the deck C, diverging rapidly downward, and the strippers L, diverging upward, is accumulated under and against such floating fingers, the latter being forced outward and upward as the quantity of accumulated grain increases, the grain being thusretaiued in reach of the bindlng arm. This construction requires the minimum extent of any devices above the top of the drive wheel, and permits the location of the binder deck far enough below the top of the drive wheel to allow the grain a sufficient fall to very materially assist in straightening it and causing it to be accumulated in good condition for the action of the binder. The shoes Il may be omitted, and such omission will not materially affect the action of the device, provided in that case, that the strippers L are sufficiently rigid to uphold the endless carrier atthe point where it should be deflected above the drive wheel, but the shoes and strippers co-operate in a desirable manner, and I prefer to use them both.

I claim- 1. In a grain harvester,in combination with the platform carrier at the grainward side of the drive wheel and the binder deck at the stubbleward side; a continuous deck extending from the delivery side of the platform carrier in an upwardly inclined direction to a point above the drive wheel; thence substantially horizontally above the latter to its stubbleward side, and thence downwardly at the stubbleward side of the drive wheel to the binder deck; andan endless carrier overhanging the portion of said deck at the grainward side of and above the wheel: substantially as set forth.

2. In a grain harvester, in combination with a platform carrier at the grainward sideof the drive wheel and the binder deck at the stubbleward side, a fixed deck extending from the delivery side of the platform carrier tothe receiving side of the binder deck, and deflected toward horizontal position at the grainward side of the drive wheel, and again deflected downward at the stubbleward side of the drive wheel; an endless carrier operating above the portion of said deck located grainward from the drive wheel and having its delivery side at a vertical plane stubbleward of the drive wheel, and deflected upward out of the direct plane between its receiving and delivery sides substantially at" the vertical plane of the said deflection of said fixed deck toward horizontal position: substantially as set forth.

3. In a grain harvester, in combination with the platform carrier at the grainward side of the drive wheel and the binder deck at the stubbleward side, a continuous deck extending from the delivery side of the platform carrier to the receiving side of the binder deck; an endless carrier overhanging at its receiving side the delivery side of. the platform carrier, and having its delivery side at a vertical plane stubbleward of the drive wheel and having its upper ply deflected upward and its lower ply free to yield upward out of the direct plane between itsreceiving and delivery sides substantially at a distance grainward from the deli very-side roller: substantially as set forth.

4. In a grain harvester, in combination with the platform carrier at the grainward side of the drive wheel, having its roller at the delivery side of large diameter relatively to the distance between the upper and lower ply of the carrier throughout its principal extent,
